(a) Rank the following decays in order of the change in atomic number Z that occurs in the decaying nucleus, from most positive (greatest increase in Z) to most negative (greatest decrease in Z). If any two decays cause the same change in Z, state this. Explain how you made your ranking. (i) Alpha decay (emission of a 4He nucleus of charge +2e) (ii) Beta-minus decay (emission of an electron of charge –e and an antineutrino) (iii) Beta-plus decay (emission...

Which of the following statements is True? (a) The valley of stability is the geographic location where many of the known nuclides were first discovered. (b), If N/Z ratio is too low , there are too many neutrons and the nuclide will undergo beta decay. (c) If N/Z ratio lies somewhere below 1 , the nuclide is stable. (d) If N/Z ratio is too high , there are too many protons and the nuclide will undergo position emission or electron...
